My heart breaks for you! I know how it feels when your child is unhappy. If you feel like you need to do something, reach out to the dorm parent, advisor, etc. and ask if they can keep an eye out for her and help in any way. IME, adults who choose to work at BS happily take on this type of task.
It is early, and odds are excellent that this will turn out fine. Good luck to all of you.
